Sitting is all he'd be doing. That blaster was in the crew cab after all.

I like that Wullfwarro got a buff. IF you can find a way to slip damage under his shields, awesome. If not well, take r2d2 crew.

Pilot suggestion
Padme Amidala- aggressive negotiator
Init 3, 1 [charge]^
After you perform an attck that hits you may spend 1[charge]. If you do, assign the Truce condition to the defender.
Truce: You may not attack or be attacked by the ship that assigned this condition. If that ship assigns the Truce condition to another ship or if this ship is the last ship in your squad, remove this card.

See that's where you're wrong. What you call the Tie punisher is actually the Punisher's tie from that one rare MCU/Star Wars crossover comic from 5 years ago. And as the punisher is basically rambo, that many gunner slots, and accompanying guns are totes legit.

I agree they could have added more dice, but you don't have to keep the results in your head because every die has the same four results.
The surges aren't there to add character they are there to maximize variation. For example rebel troopers have a 50% chance to hit where rebel commandos(same weapon more training) have a 62.5% chance to hit.
